--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Marek Polacek <mpola...@gcc.gnu.org>: https://gcc.gnu.org/g:bab669f2fc643cb1673aecd177eec1c773e9e48e commit r11-7012-gbab669f2fc643cb1673aecd177eec1c773e9e48e Author: Marek Polacek <pola...@redhat.com> Date: Fri Jan 29 11:29:25 2021 -0500 c++: Improve sorry for __builtin_has_attribute [PR98355] __builtin_has_attribute doesn't work in templates yet (bug 92104), so in r11-471 I added a sorry. But that only caught type-dependent expressions and we also want to sorry on value-dependent expressions. This patch uses uses_template_parms, but guarded with p_t_d, because u_t_p sets p_t_d and then v_d_e_p considers variables with reference types value-dependent, which breaks builtin-has-attribute-6.c. This is a regression and I also plan to apply this to gcc-10. gcc/cp/ChangeLog: PR c++/98355 * parser.c (cp_parser_has_attribute_expression): Use uses_template_parms instead of type_dependent_expression_p. gcc/testsuite/ChangeLog: PR c++/98355 * g++.dg/ext/builtin-has-attribute2.C: New test.
